WRENCH.

Application sied July 23,

To @ZZ '1v/tom t may concern.'

it known that we, Jol-IN H. PI-nrrs and HENRY F. TURNER, citizens of the United States, residing` at lVickliffe, in the county of Ballard and State of Kentucky, have invented certain new and useful Imj'n'ovements in VrencheS, of which the following' is a specification.

This invention relates to improvements in wrenches and has as its general object Vto provide a wrench which will possess all of the advantages of a ratchet wrench but will be less expensive to manufacture, less complicated, and adapted for adjustment to nuts or pipes of various sizes without the necessity of interchanginp,` parts.

Another objectof the invention is to provide a wrench so construct-ed that its jaws will be adapted to slip about the corners of a nut or about the surface of a pipe, when the wrench is swung in one direction, and will securely grip the nut or pipe, as the case may be, when the wrench is swung in the opposite direction.

In the accompanying drawings:

4 igure l is a side elevation of the wrench embodying' the present invention.

Figure 2 is a similar view illustrating` the position assumed by the adjustable jaw of the wrench when the wrench is backwardly rotated. f

"Figure 3 is a vertical longitudinal sectional view through the wrench, theadjustable jaw being shown in the position illustrated in F igure 2 of the drawings.

The wrench embodying the invention coniprises a stock which is indicated in general by the numeral l and which is formed at one end as at 2 so as to provide a. grip or handle which may be grasped for the purpose of manipulatingthe tool. The stock l is provided at its opposite end with a fixed jaw 3 which may be provided with a flat face to adapt the wrench for application to a nut, or the face of the said jaw maybe formed to provide for adaptation of the wrench to a pipe or rod.V ln order to accommodate the shank ofthe movable jaw of the wrench as will presently be explained, the stock l is formed with a longitudinally extending bore e opening at one end of the of the jaw 3, the stock at this portion being` preferably indicated by the numeral 5 for a purpose to be presently pointed out. Preferably the Specification of Letters Patent.

in diameter end as best e drawings. Also bore 4 is gradually increased from its inner end to its outer shown in Figure 3 of th for a :purpose to be presently stated the stock l is formed in its upper side at a point intermediate the ends of the bore 4 with a recess indicatedy by the numeral 6, the bore transecting this recess as shown in the said Figure 3.

The adjustable jaw of the wrench is indicated by the numeral 7 and may ybe vided with a Hat face to adapt the wrench for application to a nut or with a face adapting the wrench for application to a pipe or rod. yThe jaw 7 is provided'with a shank which is indicated bythe numeral 8 and this shank at theend adjacent its juncture its shank 8 within that the jaw may the stock l by disposingthe bore 4, and in order be adjusted, a cylindrical onto the portion 9 of the is provided with a knurled surface l1 whereby it may be conveniently rotated by lingers. It will be observed that the nut 10 is received within the recess 6 and by abutment at its ends against the walls said shank 8 and as the bore ft1sgraduallyincreased in diam- 8 may have a backward and forward play in the said bore. In the position normally assumed by the adjustable jaw and its shank, the face of the said jaw will squarely oppose the face of the jaw 3 but when the shank 8 is canted in the bore '-1 as illustrated in Figures 2 and 3 of the drawings, as when the wrench is backwardly turned while remaining in engagement with the nut or pipe to be rotated, the jaw 7 will be tilted away from the jaw 3 thus adapting` the jaws to slip about the corners nut l0 is threaded ioo adapting them to rotate freely depending upon the conditions under which the Wrench is employed. ln order to hold the javv 7 and its shank 8 in the lirst mentioned position-so that when the Wrench is forwardly swung, its javvs will grip the object engaged, a leaf spring 12 is secured at its rear end as at 13 to the back of the stock 1 and normally rests flat against the said stock, extending across the recess 6 and having its forward end deflected inwardly as at 111 to seat Within the outaivay portion side of the said stock, the deilected end 14 of the spring resting in engagement with the back o the shank 8 of the adjustable jaw and yieldably holding` the javv and its shank in the normal position above described and illustrated in Figure 1. It will be understood at this point that canting of the adjustable jaw and its'shank is against the tension of the spring 12 so that when the Wrench is backwardly swung7 its jaws will ride over the corners of a nut engaged by the Wrench and the same result of the nut or about a pipe,

tion,

will be obtained as though the Wrench were of the ratchet type. This canting is, hovvever, limited by thewall. of the bore L1, in order not to strain the spring 12 to breaking point, see Figure 3.

Having thus described the invention, what is claimed as neviT is: j

Y A. jaw comprising a stock having a tapered bore and provided with a recess transected by the bore, a movable provided with a shank disposed Within the bore for canting movement, the said shank being threaded for a portion oi its length, a nut threaded onto the said portion of the shank and received Within the recess, and a leali spring secured upon the stock bridging said recess and bearing against the back of the shank adjacent the open end of said bore and yieldably holding the shank in one directhe Wall of said vbore adapted to limit the canting movement of said jaw.

ln testimony whereof We affix our signatures. Y
